FRANCIS ET AL DRAW-OFF ARRANGEMENT FOR LIQUID CONTAINERS Filed April 30. 1929 Patented July 21, 1931 HENRY FRANCIS ANID FRANGIS OLIVER, OF HULL, ENGLAND DRAW OFF ARRANGEMENT FOR LIQUID CONTAINERS Application filed April 30, 1929, Serial No. 359,294, and in Great Britain February 9, 1929.

The present invention relates to draw-E taps or valves for barrels, casks, bottles and like liquid containers.

, According to the present invention, a pair of hollow threaded members are adapted to engage with an internally threaded cylindrical sleeve adapted to be secured to one wall of the barrel or the like container, or to the neck of a bottle or the like, one of said threaded members acting as a valve being adapted to regulate the degree of opening through said sleeve on the displacement of the other threaded member to which a tap,

cock or the like is adapted to be secured.

For the purpose of convenience one threaded member is called the valve and the other the outer member. v

Both these members are hollow, and the 0 outer member is adapted to receive at one end a tap, cook or the like, whilst at the other end it is provided with a hollow longitudinal projecting portion of smaller diameter, with perforated walls and ribs extendinglongitudinally thereof.

The ribs of this pro ect1-ng portion are adapted to engage with longitudinal ribs formed on the inner wall ofthe valve.

This valve has a closed end with radially disposed ports substantially adjacent to such closed end.

By reason of the fact that both the valve and the outer member are externally screw threaded it will be seen that on rotation of 5 the outer member in one direction, the ribs on the projecting portion of the outer member may be brought into engagement with the internally disposed ribs of the valve to rotate this and consequently displace said valve longitudinally of the threaded sleeve, to close or regulate the degree of openlng between the closed end of the said valve and the end of the sleeve.

The invention is applicable to taps for bar- 5 rels or casks or for any one of the number of purposes such as the spraying, pouring, shaking of liquids from bottles, such as, for example, scent bottles.

The invention is more particularly described with reference to the accompanying drawings, in which Figure 1 is a cross sectional view through one form of cylindrical sleeve with a valve in its closed position therein, the sleeve being mounted on the wall of the'barrel or cask.

Figure 2 shows one form of construction of tap having means for opening and closing the valve of Figure 1.

Figure 3 is a suitable form of cap or plug for engagement With the threaded sleeve when the cask is not being used.

Figure 4 is a sectional plan of the valve on the line AA of Figure 1.

Figure 5 shows a modification of the invention in its application to a scent bottle, the liquid being ejected from the bottle by means of a spray. Y

Figure 6 is a sectional plan View on the line BB of Figure 5, the spray connection being removed. 7

Figure 7 is a sectional plan view of the spray extension which is adapted to co-operate with the valve to open and close the passage for the liquid from the bottle.

Figure 8 is a detail view of the spray extension enlarged for the sake of clearness.

In the drawings a cylindrical sleeve is inclicated at 10, this sleeve being mounted in the perforation formed in a wall 11 of a cask or barrel and secured in position thereon by means of a lock nut 12. This sleeve is threaded internally, the diameter at one end 13 being greater than the diameter at the other end 14.

The end 14 of the sleeve 10 is adapted to receive a valve 15 which is in the form of a cylinder having aclosed end or head 16. This valve 15 is externally threaded for engagement with the internal thread on the end 14 of the sleeve. The valve further is provided with one or more recesses 17 in its cylindrical face whilst on its inner periphery it is provided with longitudinal ribs 18. The head 16 is of a diameter at least equal to the external diameter of the end 14 of the sleeve.

The outer member, as will be seen in Figure 2, is provided with a neck 19 at one end of a cylindrical portion 20, which is both externally and internally threaded, the internal thread receiving a tap 21 or the like means. The external thread 20 is adapted to engage with the inner thread on the end 13 of the sleeve 10.

The outer member further is provided with a hollow substantially cylindrical projection 22 perforated at 23 and having longitudinal ribs 24 provided on its outer end. The end 25 of the projection 22 is also perforated. This perforation is not shown.

lVhen the cask or barrel is not in use, a cap 26 externally threaded at 27 and having internal longitudinal ribs 28 is adapted to be inserted within the end 13 of the cylindrical sleeve 10, the cap having a closed end 29 so that no liquid can emerge from the cask. The ribs 28 are utilized to screw the cap firmly in position in the sleeve 10, whilst sealing wires are adapted to be passed through transverse bores 30 in the sleeve 10 and transverse bores 31 in the cap 26 to seal the cask or barrel.

When it is desired to obtain access to the liquid within the cask or barrel the cap 26 is removed, a cap or other means is screwed into the outer member whereupon the tap, together with the outer member, is inserted within the sleeve 10 so that the thread 20 of the outer member engages with the thread on the end 13 of the sleeve 10.

By rotating the outer member the longitudinal ribs 24 thereon engage with the longitudinal ribs 18 on the valve 15 so that as the outer member is being screwed into the sleeve 10 the valve is gradually displaced. to the left in Figure 1 thereby bringing the perforation 17 outside the end of the sleeve. In this way the valve 15 is opened and liquid is allowed to pass from the cask through the perforation 17, through the sleeve 10 into the outer member via the perforation 23 and through the tap 21.

Vhen access to the liquid is no longer desired the outer member is unscrewed from the sleeve 10. Unscrewing of the outer member automatically screws up the valve 15 within the sleeve 10, i. e. the valve is moved to the right by reason of the engagement of the ribs 18 with the ribs 24 of the outer member thereby once again closing the valve. Thus the valve is only opened when the outer member is in position within the sleeve.

In the modified form of construction according to Figures 5-8 the invention is shown in its application to a scent bottle. In this case the spray device is used for ejecting the liquid from the bottle, but it is obvious that the spray device may be replaced by a pourer,

shaker or any other device.

In the form of construction the valve is similar to the valve of Figure 1 with the exception that it is provided with a depending tube 32 which extends substantially to the base of thebottle 33.

The sleeve 10 substantially similar to the sleeve of Figure 1 but instead of this engaging with the actual neck of the glass bottle which engages with a metallic ferrule or cap 35 which surrounds the neck 34 of the bottle 33, the engagement being by way of an internal thread 36 on the ferrule and an external thread on the outer end of the sleeve 10.

In this case the so called outer member, i. e. the member corresponding to the element secured to the tap 21 of Figure 2, is the spray device 37. This spray device consists of the usual air inlet 38 which is connected to a bulb (not shown) and a spray exit 39. The spray device 37 is provided with a threaded portion 40 which is adapted to engage with the internal thread on the sleeve 10. A. tubular portion 41 depends from said threaded portion and is provided with ribs 42 which are adapted to engage with internal ribs on the valve 43. This depending portion 41 of the spray has a perforation 44 formed immediately beneath the threaded portion 40 and surrounding an internal tube 45 which is provided with a collar 46 at its lower end so that air passing through the inlet 38 may continue through the spray and into the tube 32.

If desired instead of providing the valve 43 with ribs similar to the ribs 18 in the valve 15 of Figure 1 the internal face of the cylindrical valve 43 may be formed as shown in Figure 6, i. e. with recesses 47 adapted to receive the ribs 42 of the spray.

hen the spray 37 is inserted within the sleeve 10 and is rotated therein, such rotation causes rotation of the valve 43 by reason of the engagement of the projections 42 of such spray with the recesses 47 of the valve and opens the valve to allow of passage of liquid within the bottle 33 into the chamber bounded by the threaded wall of the sleeve 10. The liquid then passes through the perforation 44 and up through the spray whence it is sprayed into the atmosphere through the orifice 39.

Liquid may only pass into the spray when the valve is displaced downwardly in Figure 5, i. e. when the spray 37 is secured in position. 011 removal of the spray the valve is automatically closed.

The ferrule or cap 35 of Fig. 5 may be eliminated altogether in which case the sleeve 10 may be mounted on the neck of the bottle. A stopper similar to the cap or plug 26 of Fig. 3 may be provided, and this stopper may have the usual ornamental head.

hen this stopper is in position within the sleeve 10, the bottle or other container will have the same external shape or configuration as a similar bottle without the valve of the present invention, i. e. the external sh ape of the bottle remains unaltered.

At the same time, when the stopper is in lllll adapted to contain perfume or other highly volatile liquids and is a definite prevention of any loss due to evaporation of the liquid. A similar advantage is also derived in bottles containing poison.

We declare that what we claim is 1. A closure for bottles comprising an open ended internally threaded ferrule adapted to encircle the neck of a bottle, an internally and externally threaded sleeve, the external thread of which engages with the internal thread of said ferrule, a valve having an upstanding externally threaded annular portion engaging with the internal thread of said sleeve, a liquid draw off member which is also threaded to engage with the internal thread of said sleeve, and interengaging means between said draw Off member and said annular portion of said valve to regulate the degree of opening of said valve according to the position of said draw off member relatively to said sleeve.

2. A closure for bottles according to claim 1 wherein said interengaging means comprises a tubular projection on said draw 01f member extending below the threaded portion thereof, and ribs on said tubular projec tion adapted for engagement between pro jections on the inner wall of said annular portion of said valve.
